Help - boundaries. Am I doing th ewrong thing?

[Surfer]

The overthinking and internal narration is a sign of attachment I am afraid. You wouldn't overthink about someone you have no attachment to. It's also hard to detach when living together. But it's something you keep working on. I think of it as being in that head space when you are able not to be taken on the rollercoaster as she spews.
